That first patch was a rough one.  Here is a better patch;
it avoids recalculating all the multiline data in some cases
when it's not needed.

It can probably be improved still further, but this one avoids
slowdowns when editing inside an area covered by a multiline
regex.  (To test, I run it on a tenfold concatenation of all
of nano's C source files.)

If you can, please test.
